After few years working with the version 17 under Win10, I upgraded to Win 11 few months ago - everything worked fine. Since 3 days I get continously the same error message "FTP error: Failed initialization". No changes on my computer, no changes in the settings of the web-host.

The helpline basically says: version 17 is not supported under Win11; so we can not help.
But - it worked fine for about 2-3 months.

Anyone with the same problem? Any solutions yet?
